EL-LSTON SMITH AND GEORGE W. SNOOK, OF BUFFALO, NEW YORK, ASSIGNORS OF ONE-THIRD 'I'O WILLIAM E. PECK, OF BUFFALO, NEW YORK.

OLA-MP FOR BAG-HOLDERS.

Application filed September 8, 1913.

To all whom it may concern:

Be it known that we, ELLs'roN SMITH and GEORGE W. SNOOK, citizens of the United States, residing at Buffalo, in the county of Erie and State of New York, have invented certain new and useful Improvements in Clamps for Bag-Holders, of'which the following is a specification.

The invention relates to an improvement in bag holders of that type designed to be secured to a suitable support and adapted to receive and support a bag or the like in posi tion to permit its convenient filling- The main object of the present invention is the provision of a bag holder including a clamping element designed to be removably secured to an upright or support, to which clamp is secured a distending ring about which the mouth of the bag is removably clamped in a simple and convenient manner, the construction including arms for the temporary support of empty bags and a conveniently-located twine holder.

The invention in its preferred form of details will be described in the following specification, reference being had particularly to the accompanying drawings, in which- Figure 1 is a view in elevation of the improved bag holder. Fig. 2 is a section on line 2-2 on Fig. 1. Fig. 3 is a broken plan,

partly in section, the line of section being on the line 33 of Fig. 1. Fig. 4 is a section on line 4% of Fig. 1.

Referring particularly to the accompanying drawings, the improved bag holder comprises a supporting web 1, in the form of an upright plate provided at one end with an approximately semicircular flange 2 and at the opposite end with a transverse section 3, the latter extending equally and in opposite directions to the web 1. The web 1 is preferably an integral casting and formed with horizontal reinforcing flanges 4;, as shown.

Pivotally mounted at the respective ends of the transverse section 3, as by pivot bolts 5, are clamping plates 6, the latter being connected for adjustment by threaded rod 7 on which, beyond each plate, are mounted adjusting nuts 8 provided with hand wheels 9. A spring 10 is coiled about the rod, bearing against the respective plates, said spring serving to normally spread the plates. Near the outer or free end of each plate is Specification of Letters Patent.

mounted through a ball and socket connec- 131011 11, what we term a clamping jaw 12, the jaws being cone-shaped and their base portions formed with spurs 13.

Pivotally mounted at 1 1- to the lower edge of the web 1 is a brace rod 15, having its free terminal pointed at 16, a spring 17 connecting the rod with the section 3 and serv- 1ng to normally elevate the rod to an inoperative position. when not in use.

Secured within the flange 2 through the medium of bolts 18 is what we term the bagdistending ring 19, comprising an annular member having an outwardly-extending rib or flange 20 at the lower edge, and a flaring or filling flange 21 at the upper edge. Pivotally mounted on ears 22 projecting from opposite sides of the web 1 are clamping arms 23, said arms being shaped in part to encircle the distending ring immediately above the flange 20, the ends of the arms remote from the web being provided with handles 24, adapted when the arms are in clamping relation to the ring to be brought into relative proximity diametrically opposite the web, as shown in Fig. 1, the terminal of one of the arms beyond the handle being provided with a locking lever 25 formed with an opening to engage a stud 26 on the other handle, whereby the arms may be locked in clamping relation to the ring. Springs 27 are secured to the web and bear against the respective arms, said springs serving to normally maintain the arms spread or in non-clamping position, the ends of the arms toward the clamping plate being formed with off-set projections 28 to engage the web 1 and limit the open position of the arms.

Bag-holding arms 29 are pivoted at 30 on the flange 4, being shaped to encircle the distending ring when not desired for use, the forward ends of the arms having upstanding projections 31 to be engaged by a ring 32 carried by one of the arms, to secure the arms in inoperative position. The arms 29 are, when the device is in use, adapted to be swung open to provide a support for a number of empty bags, whereby such bags are conveniently located to be withdrawn by the operator when desired.

A twine holder 33 is pivotally supported on the upper edge of the web comprising a plate 34 adapted to bear upon the web and an upright spindle 35 to receive the twine ball 36. The plate 34 is slotted at. 37, .to permit the twine holder as an entirety to be turned rearwardly on its pivot, out of the way, when not desired to be used. Handles 38 are secured to the clamping plates 6 for convenience in handling the device. v

In use the b,ag.;3,9 is arranged :With its open end exteriorly of the distending ring, the arms 23 being moved to'and locked in clamping position, to secure the. bag as showninFig. lg thedevice as awhole having been initially secured to an upright, as 'apost 40 or the like, by clamping the jaws 12 thereon through the medium of the clamping; nuts 8, the rod 15 having been turned downwardly at an angle; and its pointedterminal 16 forced into the post, all as clearly shown in Figs. 1 and 2. In this position the bag may be conveniently filled and tied immediately below the dis- -'tending ring by the twine from the ball 36. When not in use the parts assume the positionspreviously described in which the de- -vice; as an entirety presents no obstructions to its convenienthandling or storage.

w ll denotes hooks bolted to the clamping plate 6, hookin'gdownward halfway of 38, so by removing the rod opening clamping plates the device can be hooked over a board, for instance the side of a bin or wagon box.

- Having thus described our invention, what we claim and desire to secure by Letters Patent, is I 1 1 1. Aclamping and supporting means for b'ai'gholders comprising a web, clamping Tplates; pivotally connected to the web, a threaded rod passing loosely, through .the plates beyond their pivots, means cooperatthreaded rod terminals to ininduce clamping cooperation of said plates, a brace rod underlying the clamping plates and pivotally connected to the web, and a spring connecting said rod and web.

. 3. A clamping and supporting means for bag holders comprising a web, clamping plates p'ivotally connected to the web and adapted to be moved into relatively parallel positions at right angles to the web or into an alined position, and supporting elements carried by the plates for cooperation with a support when the plates are in an alined position.

4. A clamping and supporting means for bag holders comprising a web, clamping plates pivotally connected to the web and adapted to be moved into relatively parallel positions or into an alined position, and hooks carried by the plates for cooperation with a support when the plates are in an alined position.

In testimony whereof, we afiix our signatures in presence of two witnesses.
